May be it's a stupid question but I can't figure it out.
according to Eulers Relationship:
ej[tex]\alpha[/tex]=cos[tex]\alpha[/tex]+jsin[tex]\alpha[/tex]
on the other hand I have equation:
Vt=V0cos wt
and it can be rewritten as:
Vt=V0ejwt
where V is voltage in AC (see link below)
http://hyperphysics.phy-astr.gsu.edu/Hbase/electric/impcom.html"
In this case cos wt is at the place of cos[tex]\alpha[/tex], but what I can't understand is, where did jsin [tex]\alpha[/tex] go?
